RAILWAY SIGNAL DEVICE.

AppIication filed June 5, 1922.

To (11K to hem it may concern Be it known that we, HENRY WILLIAM lRonLIno, ANDREW G. KERN, Jenn G. BAUER, and Josnrii CATALANO, Jr, citizens of the United. States, residing at New @rleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Railway Signal Devices; and we do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to railway signal devices and has for anobject to provide an improved device in the engine cab for notifying the engineer plainly of the position of the semaphore guarding the block which he is about to enter.

Other objects of the invention are to simplify the construction of signals, to provide a device for securing a high degree of safety in the operation of railroad trains and the like, to enable the device to be installed in connection with semaphore signals and the locomotive structure without requiring any alteration in standard constructions and to provide a device which is simple in its construction, reliable in its operation and economical to make.

With the foregoing and other objects in view, the invention will be more fnlly described hereinaiter, and will be more particularly pointed out in the claims appended hereto.

In the drawings, wherein like symbols refer to like or corresponding parts through out the several views,

Fig. 1. is a diagrammatic view showing the railway track in section with a semaphore signal and a locomotive equipped with a device according to the present invention.

Fig. 2. is a sectional view on an enlarged scale of the circuit controller.

Fig. 3. is a transverse sectional view taken on the line 3-3 in Fig. 2.

Fig. i. is a similar view taken on the line %4 also in Fig. 2.

Fig. 5 is a central section taken through a relay employed.

Fig. 6. is a circuit diagram showing the relation of the various units in an open circuit arrangement, and

Serial No. 565,958.

Fig. 7. is a similar view of a closedcircuit arrangement.

Referring more particularly to the drawings 1 designates generally a locomotive upon, the track 2 and 3 indicates a standard supporting the semaphore signal t.

According to the invention a pair of bevel gears 5 are adapted to mesh and be rotated by changes in the position of the semaphore arm, these gears being situated at the base,

of the standard 3 and in connection to rotate a shaft 6 that extends transversely beneath the rails 2. Bearings 7 support the shaft which carries a pair of trip arms 8 and 9 projecting at substantially 90 degrees apart.

Upon thelocomotive are carried controllers 10 and 11 having fingers 12 and 13 adapted to project in the path of the arms 8 and 9 to be actuated thereby. The'controllers are in circuit with relays 14C and 15 in the engine cab or at other suitable pointsv therein and these relays are in turn in circuit with signal lamps 16 and 17 also carried by the locomotive. It is to be understood that the relays and lamps are shown only diagrammatically in Fig. 1 and in practice they would probably be located in the engineers side of the cab directly in front of the-throttle lever where the lamps would come at all times under the observation of the engineer.

Referring more particularly to Figs. 2, 3, and 4;, one of the controllers 11 is shown in detail embodying a shaft .18 which projects up axially through the controller casing 11 and is journaled in bearings 19 and 20 carried by the closed end of the casing and by the removable cover 21 which is secured to the open end of the casing as by the screws 22. The shaft 18 extends downwardly below the casing and the cover 21 and carries upon its lower end the arm 18.

Within the casing is a drum 23 secured to the shaft 18 as by the use of a pin 2a. This drum or conductor body 23 is made of brass or other appropriate conducting material and is provided with diametrically disposed pockets 2i and 25 for receiving the their inner faces to conform to the curveture of the drum. These brushes are provided with pins slidably received in hollow bosses 3i projecting inwardly trom insul ating plates 32 carried by the cursing 11. Binding screws or bolts 33 are threaded through the casing and through the plates 32 and are connected to the brushes y coil springs 3% which normally press the brushes yielding against the surface of the drum.

Binding nuts 35 not to loclr the bolts in idjusted position thus permitting of u regulation of the tension of the coil sprin The shaft 18 below the cover 21 carries an arm '36 normally held in an internie l ate position by two oppositely acting springs 38 attached to the arm 36 end to the studs 39 on the cover. The arm has bifurcated ends 4.0 adapted to receive at tightening bolt- 41 by which the arm is effectively gripped to the shaft 18.

Referring now to Fig. 5, the improved relay is shown to consist of a magnet r solenoid l2 situated above and resting upon the casing 15 which is provided with an opening in its upper end to receive the down turned flange 43 and the solenoid base. This flange 43, together with the upper portion of the solenoid. and elongated bearing l turned upwzirdly from the bottom of the casing, provide for slidebly receiving and properly centering a core 45 having an insulated lower portion 46 made ct fl re or some other suitable material, a brass or other good conducting intermediate section 17 and a steel or other metallic upper section 4-8 adapted to be cut by the magnetic lines of force. The fibre or insulating section 46 is provided with a depressed portion or groove 49 to receive the rounded free ends of a pair of contact lingers 50 and 51 secured by binding bolts or screws 52 and 53 projecting through insulatingblocks or and c 'posed on the exterior of the casing for con ling to the circuit wires. A similar groove is made in the interme- A. lever as is pivdiate brass section 1-7. oted intermediate its ends in a bracket 57 depending from the bottom of the casing" This lever is provided vith a rounded head 58 adapted to engage beneath the lower end of the solenoid core, while the opposite end of the lever receives a chain 59 or the like.

Referring to Fig. 6 the battery 60 is shown to be connected in circuit with the two controllers l0 and 11, the two controllers being in parallel. The loads 61 and 62 extend. from one side of the battery 60 to like brushes on the two controllers. The opposite brushes or the respective controllers are connected by wires 63 and to the upper ends of the solenoid windings 42. The return wires 65 and 66 connect in common with the opposite side of the battery 60. i

The contact fingers 51 of the respective relays are connected by conductors 6'7 and.

- ii will be is l lQlI and turn-ed s connection 1 i or the drum sutt-he insulted segments 26 ct with the brushes 28 and i 1 D the circuit to be closed through the brass l and? 251, oerniitt'n drum. The circuit will be completed loLov-Js; beginning et'the bettery 60 the current will flow through the lead 61 to the rush through the drum ll to the opposite brush 23 and thence by way oi the wire 63 to ant through the solenoid completing the the wire noid d2 w cause di 50 and 51 gageinent I brass inn mediate section ll".

This restoration zccomplished by the engineer drawing upo; the chain 59 which c uses the lever 56 to rock and its rounded head 58 to engage beneathand lift the core to the position shown in Fig. 5.

it will be appreciated from the foregoing at the invention provides for bringing the als closely to the attention of the engiand to enable him to ascertain with prec ion the condition of the road or block ahead and thereby surround the operation ot trains with greater sa'tety.

We have illustrated and described a preferred and satisfactory embodin ent of our e tion, but it is obvious that changes may be made ierein within the spirit and scope t as defined in the appended claims.
